But the established exciting system using this method, the information which ignored personalized individualized can be furnished.

중국의 북한 핵문제에 대한 기본인식

李哲源 한국교통대학교 2017 한국교통대학교 논문집 Vol.52 No.-

朝核问题延续半个多世纪至今,呈现出久拖不决并越来越棘手的趋势。特别是在朝鲜已经拥核并试图抛 弃元核化承诺的背景下,半岛局势更加波请云诡,朝核问题引发的变局正在向纵深演进。在此过程中,朝鲜 的战略选择和美国的对朝决策将起着决定性的作用,直接影响到东亚地区的和平与稳定。首先,朝核问题短 期内依然元解,朝鲜半岛局部动荡或将成为一种常态。近些年来,朝鲜半岛这个冷战时期遗留的“活化石”在 朝核问题这副催化剂的作用下逐渐复苏。美国则坚持对朝敌对政策,固守制裁思维,不愿意根本放弃对朝 “政权更迭”打算。在双方严重对立的政策取向下,美朝之间的互信难以建立,双方在朝核问题上无法找到最 大公约数,相互对抗在短期内难以消挥。为确保自身绝对安全,美朝战略竞争将催生并加剧双方的安全困 境,在朝核问题上迎头相撞的可能性增大。从历史上看,朝核问题因美国而起。长期以来,朝鲜也寻求将美 国作为解决朝核问题的首要对象。但美国对朝鲜政权的敌视政策没有根本消除,一段时间内,美国对朝政策 不会有根本改变。如果朝核问题长时间无法取得实质性进展或出现新的恶化,美国的对朝政策困境将进一步 凸显,即多边会谈和双边对话都难以成功说服朝鲜弃核,而通过军事手段解决朝核问题的可行性则受到各种 因素的严重制约。面对朝鲜要求签署和平协定的呼吁,对于坚持日韩同盟战略框架的美国,通过和平谈判来 一揽子解决朝核问题需要付出重大的政治代价.

In the Modern times, after the Opium war(1841) and it’s aftermath the Chinese society had broken her own traditional life style and ideology. From the points of Chinese view, these currents were the very things that had not experienced during the thousands years. As the foundation of the Confucion ideology and the life style had been attacked by the Western material civilization could not had maintained themselves. Especially the Shanghai, open habor city area, the popular culture also had changed following these currents that the Western culture came to the ordinary things more and more. We can object these currents on the focus of the historical materials and the socio-political methods.

固眞飮子가 galactosamine으로 유발한 흰쥐의 간중독에 미치는 영향

원철환,정승현,임성우,신길조,윤상협,이원철 동국대학교 한의학연구소 1997 東國韓醫學硏究所論文集 Vol.6 No.1

최근 간질환에 대한 진단과 기술의 비약적인 발전에도 불구하고 치료방법론에서는 그 해결이 모호한 상태에 있다. 실험적으로 간중독을 유발시킨 동물에 약물을 투여하여 그 약화를 입증하려는 노력이 진행되고 있다. 이에 저자는 固眞飮子가 간독성의 완화효과에 미치는 영향을 관찰하기 위하여 固眞飮子추출물을 투여한 흰쥐에 galactosamine으로 간독성을 유발하고 간조직내 glutathione과 과산화지질의 함량, 혈청중의 GOT, GPT, γ-GPT, ALT, LDH의 효소활성측정 및 혈청중의 bile acid함량을 측정하여 다음과 같은 유의한 결과를 얻었다. glutathione의 함량은 固眞飮子을 전처치한 실험군에서 유의성 있게 증가하여고, 과산화지질, 혈청중 GOT, GPT, γ-GPT, ALT, LDH, bile acid는 고진음자를 전처치한 실험군에서 유의성있게 감소하였다. The purpose of this study is to observe the protective effect of Kojinyumja on serum reaction and hepatic tissue in galactosamine treated rats. In this study, the experimental rats divided four group(Normal group, Control group, Sample A group, and Sample B group): Under the same condition, normal and contro1 group were administered water, sample A, B group were administered Kojinyumja for 8days. And then, Coth control group and Sample B group were injected to abdomen with galactosamine for 1day. The rates of glutathione, lipid peroxide, GOT, GPT, γ-GTP, ALP, LDH, and contents of bile acid level were measured. The results are as follows: The glutathione rate significantly increased in sample group, the others(lipid peroxide, G0T, GPT, γ-GTP, ALP, LDH, bile acid) significantly decreased in sample group.

政党外交是政党政治在国际事务中的延伸,是一个政党由国内走向世界的过程. 在政党政治中,政党承担着政 治发动机和政治调解器的功能,政党对国家的内政外交基本走向和经济社会的发展起决定性的作用. 从政党自身 发展的逻辑上看,政党外交一项重要的任务,就是要通过与世界各国政党的交往,总结人类社会发展规律·社会 主义建设规律和执政规律,以及外国各类执政党的执政理念和方式,努力借鉴一些外国政党在治党·治国·理政方 面兴衰成败的经验教训,提高执政水平. 一方面,通过与欧美主流政党的交往,借鉴治国理政的经验和教训,探 索总结政党执政的一般规律,实现科学执政. 欧美主流政党多是老牌的执政党,有着近百年的历史和执政经验, 对社会治疗·经济发展·危机管理等方面有着成熟的经验和做法,对执政规律有着良好的驾驭能力,既有成功的经 验,也有失败的教训. 这些对执政时间较短的中国共产党来说,无疑有着诸多可以借鉴的成功经验. 另一方面, 学习和借鉴国外政党反腐败·党内民主建设·组织建设等自身建设的成功做法. 如新加坡人民行动党的反贪机制, 古巴共产党的党内民主建设等,都对中国共产党的自身建设产生了积极的影响. 通过政党外交,使党在重要战略 机遇期进行科学的战略部署,从容应对社会敏感和重大问题.

UASB 공정에 의한 고농도 축산폐수 처리시 유기물 제거와 메탄생성에 관한 연구

원철희,김승호,박은영,임재명 江原大學校 産業技術硏究所 2002 産業技術硏究 Vol.22 No.B

This research was performed to investigate the COD removal efficiency and methane production in slurry-typed swine wastes using UASB(upflow anaerobic sludge blanket)reactor. The USAB reactor was operated from 0.8 through 3.3days of HRT in a range of 3 to 15 kg TCOD/m³/day of volumetric organic loading rate. The removal rate of TCOD was increased with the increase of the HRT. The removal rate of TCOD at an HRT over 2days, became greater than 68% with the methane contents being from 70 to 80%. Methane production rates were increased from 0.27 to 0.36 m³CH₄/kg CODrem. as HRTs were increased from 0.8 to 3.3days.

UASB 공정에 의한 슬러리형 돈사폐수의 처리

원철희,김병욱,한동준,임재명 한국물환경학회 2004 한국물환경학회지 Vol.20 No.6

This research examined the treatment efficiency and methane production rate in treating slurry-type swine waste using UASB (upflow anaerobic sludge blanket) reactor. The UASB reactor was operated at an organics volumetric loading rate (VLR) of 2.6-15.7 ㎏COD/㎥/day. A stepwise increase of the VLR resulted in a temporary deterioration in the COD removal rate in UASB reactor but recovered quickly. The COD removal rate were 65-70% for VLR up to 5 ㎏COD/㎥/day. When organics VLR was 10 ㎏COD/㎥/day, the COD removal rate decreased sharply and there was loss of 17.537g of the seeding biomass due to sludge washout. This result indicated that the UASB system cannot be adapted to more than 10 ㎏COD/㎥/day of VLR. As the organic load increased from 2.6 to 15.7 ㎏ COD/㎥/d, the biogas production rate varied from 3.2 to 10.8 L/d and the methane conversion rate of the organic matter varied from 0.30 to 0.23 ㎥CH₄/㎏ COD_(removed). The methane content showed the range of 70.1-81.5% during the experimental period. The volatile solids (VS) removal efficiency was similar at the low VLR (< 5 ㎏COD/㎥/day), but it decreased sharply at the high VLR (> 5 ㎏COD/㎥/day). The VS reduction rate was, moreover, large those of COD. The result shows that hydraulic retention time above 2 days is essential in case of treating wastewater containing 1% of solids.

X선 CT 영상으로부터 인체의 기관지 모델의 개발

원철호,노철균 한국센서학회 2002 센서학회지 Vol.11 No.5

본 논문에서는 X선 컴퓨터 단층 촬영으로부터 획득된 기관지의 3차원 영상으로부터 기관지의 구조 및 형태 정보를 추출할 수 있는 가능성을 조사하고, 분진 침착 모델의 수학적인 개발과 실험적인 검증에 사용될 수 있는 물리적인 공동 주형 모델을 개발한다. CT로부터 획득된 영상으로부터 수학적 모폴로지 기법에 의하여 폐의 기관지 영역을 검출한다. 검출된 폐의 기관지 영역의 체적 데이터를 3차원 공간상에서 나타낼 수 있는 표면 데이터를 STL(streolithography) 파일로 변환한 후에, 고속 프로토타입 기기에 입력하여 3차원 입체 형상을 제작한다. 이때 기존의 기관지 팬텀과 실제 정상인으로부터 획득된 CT 영상으로부터 각각의 공동 주형 모델을 제작하게 된다. CT 스캔하여 얻어진 원래의 영상과 제작된 공동 주형 모델을 CT 스캔하여 얻어진 영상에서의 기관지 영역의 단면 직경을 비교하여 생성된 폐 기관지 모델의 유용성을 검증하였다. In this paper, we investigate the potential for retrieval of morphometric data from three dimensional images of conducting bronchus obtained by X-ray Computerized Tomography (CT) and to explore the potential for the use of rapid prototype machine to produce physical hollow bronchus casts for mathematical modeling and experimental verification of particle deposition models. We segment the bronchus of lung by mathematical morphology method from obtained images by CT. The surface data representing volumetric bronchus data in three dimensions are converted to STL(streolithography) file and three dimensional solid model is created by using input STL file and rapid prototype machine. Two physical hollow cast models are created from the CT images of bronchial tree phantom and living human bronchus. We evaluate the usefulness of the rapid prototype model of bronchial tree by comparing diameters of the cross sectional area bronchus segments of the original CT images and the rapid prototyping-derived models imaged by X-ray CT.
